Might not be what you consider to be the greatest, but I always love George Foreman, he is criminally underrated. Wins Olympic gold and then absolutely smashed through the division back in the day in terrifying fashion. Demolished some really good fighters and was only really undone by his mental weaknesses at the time and the brilliance of Ali.
Then he takes 10 years away from boxing, just as he's entering his physical prime, comes back in his late 30's to fund his community centre and slowly works his way back to the top. Takes on a prime Holyfield and gives him a really tough fight, displaying that he had one of the most ridiculous chins in boxing history (Holyfield also says he was never hit as hard in his life and in one round thought all of his teeth had been knocked out). Gets another shot against Tommy Morrison who went from an aggressive come forward slugger to a mobile outside fighter, he wanted none of that smoke and won on points.
Finally he gets the fight against Moorer, bides his time and completely out psyches him, just as Ali did to him 20 years earlier. Sparks him out wearing the same shorts he lost to Ali in, with Jim Lampley also giving one of the greatest calls in the background. Then he till goes on to defend the belt, I think there was a suspect decision in there in his favour, but the consensus is that he was robbed of a decision against Shannon Briggs in his final fight.
He was technically underrated, had ridiculous power (the videos of him hitting the heavy bag are a sight to behold), had a crazy good chin where if you see videos of him these days he still has all his faculties unlike a lot of the other legends from his era ended up like. A young physically primed Foreman, with the temperament and discipline of the Old Foreman would have been insane.
